Environmental abrupt change

[reason] due to the sudden change of the growth environment, the plant can not adapt well, resulting in poor plant growth.

[countermeasures] when a plant is transplanted or the growth environment changes, it should create an environment similar to its original growth environment, and slowly adjust it to adapt to the transition period.

Too much watering

[reason] too much watering of yew bonsai will lead to yellowing of leaves, dark yellow and dull young leaves, and withering of the top of new shoots.

[countermeasures] Control the amount of water and gently loosen the basin topsoil with hard and blunt objects to make the basin soil breathable and move to a place where dew can be accepted every night.

Long-term water shortage

[reason] the yew bonsai is short of water for a long time, which will lead to dry leaves, insufficient water quality and yellowing.

[countermeasures] watering should be thoroughly watered once, dry and wet. The topsoil of basin soil is dry, but the middle soil is not necessarily short of water. Watering can be combined with chemicals to prevent root rot.

Sun exposure

[cause] the sun is too strong, the transpiration of plants is too strong, and the speed of root water replenishment is insufficient, which leads to the lack of water on the leaves of plants and wilting and yellowing.

[countermeasure] the yew can be restored by spraying water on the leaves of the yew.

Air drying

[reason] the bonsai of the yew was placed at the air outlet of the air conditioner, which increased the water evaporation on the leaf surface of the yew, resulting in rapid dehydration of the branches and leaves of the yew, curling and drying up the leaves, and poor growth phenomena such as wilting and sagging.

[countermeasures] if you turn on the air conditioner in the air conditioner room every day, you should spray the foliar surface every day, maintain the foliar humidity, and put a basin of water in the room.

Lack of sunshine

[reason] the photosynthate of Taxus yew bonsai can not supply the root system, which makes the root system lack of nutrients and leaves yellowing and leaf loss.

[countermeasures] put it on the balcony or outside in the morning or evening and do it every few days.
